Sahih Muslim Book 10, Hadith Number 3707.

Chapter : Forbiddance of al-Mubiqala, and al-Muzabana, and al-Mukhabara and the sale of fruits before their good condition is clear, and al-Mu’awama, i.e., the sale for some years.

Jabir b. Abdullah (Allah be pleased with them) reported that Allah’s Messenger (may peace be upon him) had forbidden Muhaqala and Muzabana, Mukhibara and the sale of fruits until their good condition becomes clear, and (he commanded) that (commodities) should not be sold but for the dinar and dirham except in case of araya.
